IMPROVEMENT IN OIL-EJ ECTOPLS.

Specification forming part of Letters Patent No. 16,925, dated March 21,1865.

To all whom it may concern:

Be it known that. I, GEORGE M. MOWBRAY, of Titusville, county ofCrawford, and Stati of Pennsylvania, have invented a new and usefulImprovement in Ejectors for Oil and other Wells; and I do hereby declarethe following to be a full and exact description of the same, referencebeing had to the accompanying drawings, making part of this specication,in which- Figure l is a vertical section of a portion of an ejectingapparatus illustrating my invention. Fig. 2 is a plan of the couplinghereinafter described.

l Similar letters of reference indicate corresponding parts in bothgures.

The object of this invention is to provide means whereby the blast-pipeof an ejector can be adjusted in relation to the eductionpipe withoutdisturbing the seed-bag or other packing device, within which the saidpipes are inclosed, to prevent the passage of water around them.

The invention consists in the employment of a coupling at one or bothends ot' the seedbagv or other packing device, to which coupling theeduction-pipe is securely attached by a screw-thread or other suitablemeans, and through which coupling the blast-pipe passes in astuffing-box, so as to admit ot' railing, lowering, or turning' it ifnecessary, without any disturbance of other parts and without a 1ypassage ot' water around the pipes.

The following description will enable any one skilled in the art towhich my invention appertains to fully understand and use the same.

In the drawing, Arepresents the blast-pipes, and B the eduction-pipe. Urepresents a seedbag, employed in customary manner to prevent anydescent of surface water or ascent of oil around the pipes. Instead,however, of attaching the said seedbag immovably io both the pipes, Iemploy a coupling, D, to connect each end oi' the seed-bag to the pipes.The eduction-pipe B may bc secured to the coupling by a screw, as shownat b, and remains stationary.

The blast-pipe A works through a stutiingboX, E, so as to preserve aconstantly tight joint, while permitting the said pipe to Le moved up ordown or turned upon its axis, it' necessary. I am thus enabled, withoutany disturbance of the packing and without moving the eduction-pipe, toadjust the blast-pipe in relation to the eduction-pipe, as may benecessary to adapt them to operate with tle best possible effect.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

rlhe coupling D, when combined with a stuffing-box, E, so constructedthat while one pipe is iixed another may be moved in the stuffing-boxwithout disturbingthe seed-bag or other packing, substantially as hereindescribed, and for the purposes set forth.
